A method for making a color filter substrate includes the steps of: forming barriers on a substrate; placing an ink having a surface tension of 20 to 60 dyne/cm onto regions between the barriers; and curing the ink to form color filters. The volume of the ink charged onto one region is three to ten times the volume of the region. A color filter substrate is produced by the above-mentioned method. A liquid crystal device includes a pair of substrates and a liquid crystal encapsulated between the pair of substrates, wherein one of the pair of substrate is the above-mentioned color filter substrate.

A method for forming spacers according to the present invention is a method for forming the spacers on a substrate, comprising the steps of: supplying adhesive at a position for forming each of the spacers on the substrate by an inkjet system; dispersing beads, each bead having a diameter corresponding to the height of the spacer, so as to adhere the beads to adhesive; and removing the beads that are not adhered to the adhesive from the substrate. A manufacturing method for a color filter having spacers according to the present invention, the method comprises the steps of: forming a color filter by forming on a substrate at least a light-shielding layer having plural apertures and a colored layer having colored portions arranged in each of the apertures of the light-shielding layer; supplying adhesive made of a curable resin composition in regions overlapping the light-shielding layer on the color filter by an inkjet system; dispersing beads on the color filter so as to stick the beads to the adhesive; and removing the beads that are not adhered to the adhesive from the color filter. Furthermore, a liquid crystal element according the present invention comprises: a pair of substrates; and liquid crystal clamped between the pair of substrates, wherein one of the pair of substrates is a color filter having spacers made by the above-mentioned manufacturing method and the distance between the pair of substrates is maintained by the spacers.
